问题 单项选择题

李娜说,作为一个科学家,她知道没有一个科学家喜欢朦胧诗,而绝大多数科学家都擅长逻辑思维。因此,至少有些喜欢艨胧诗的人不擅长逻辑思维。

以下哪项是对李娜的推理的最恰当评价?()

A.李娜的推理是正确的。

B.李娜的推理不正确,因为事实上有科学家喜欢朦胧诗。

C.李娜的推理不正确,因为从“绝大多数科学家都擅长逻辑思维”,推不出“擅长逻辑思维的都是科学家”。

D.李娜的推理不正确,因为合乎逻辑的结论是“喜欢朦胧诗的人都不擅长逻辑思维”,而不应当弱化为“至少有些喜欢朦胧诗的人不擅长逻辑思维”。

E.李娜的推理不正确,因为创作朦胧诗需要形象思维,也需要逻辑思维。

答案

参考答案:C

解析:

题干推理的根本问题是,词项“擅长逻辑思维”在前提中不周延,但在结论中却是周延的,即存在着“概念扩大”的错误。选项C正好指出了这个问题。其他选项均不得要领。
